Showcase of initial support for word clouds and data scrapping (and the usual newbie questions)

by Offray Vladimir Luna CÃ¡rdenas

Hi all, On [1] you can see a small video showing the support for word clouds and data scrapping from Twitter for some public profiles (including mine). As you can see the visualization is embedded on grafoscopio trees/documents that provide context for the scripts and combine them with other documentation. You can create your own visualization by running the code at [2] and changing the profile name. [1] https://archive.org/details/gfcp-wordclouds-initial.mp4 [2] http://ws.stfx.eu/DVG4C8VFON1L So here are my usual questions: a) The code that puts an image in a name cloud accepts only png images and when the avatar has jpeg images I got an error. There is any way to make the RTNameCloud to work with jpg or to convert it to png. I was looking at Sven's documentation[3], but I can't make it work in my context (jpeg is taken from the web and converted to png without using the file system). [3] https://medium.com/concerning-pharo/elegant-pharo-code-bb590f0856d0 b) There is any way to go beyond 19 tweets. In recent conversations with Paul[4] he taught me how to extract tweets properly from a page using ZnClient, but it gets the last 19. There is any way to make ZnClient to go beyond that initial request and get, lets say 100 or more tweets? [4] http://forum.world.st/Data-scrapping-in-pharo-Extracting-tweets-contents-td… Thanks as always for keeping Pharo/Moose and their communities awesome! Cheers, Offray

Re: [Pharo-users] Data scrapping in pharo: Extracting tweets contents

by Offray Vladimir Luna CÃ¡rdenas

Paul, Thanks, that's pretty much what I'm looking for! Your clue raises a new question: by default I get only the last 19 tweets from someone. There is any way to tell ZnClient to load more data, similar to what you do when you scroll down the twitter page? Sven, any suggestion here?

When you look at the Date class comment you'll see that they are timespans (a Start + a duration ) and not moments in time, like the time on a clock on a certain day. What you want is probably an instance of DateAndTime.

Re: [Pharo-users] String operations

by Tudor Girba

In the Moose configuration, there is a CollectionExtensions that allows you to do this: 'BormParticipant' removePrefix: 'Borm' "-> 'Participant'". 'BormParticipant' removeSuffix: 'Participant' "-> 'Borm'" For Pharo 5, we should move these extensions to Pharo.
